  sched_ext: Remove unused code in the do_pick_task_scx() (2025-12-15 05:53:49 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v6.19-rc1

- Fix memory leak when destroying helper kthread workers during scheduler
  disable.

- Fix bypass depth accounting on scx_enable() failure which could leave
  the system permanently in bypass mode.

- Fix missing preemption handling when moving tasks to local DSQs via
  scx_bpf_dsq_move().

- Misc fixes including NULL check for put_prev_task(), flushing stdout in
  selftests, and removing unused code.
